• Anyone looking to save money on expensive coffee shop drinks.
• Folks who appreciate a smooth, less acidic coffee experience.

What to check first

Brewer type and filter type

This is less about a “brewer” and more about your container. A mason jar, a pitcher, anything that holds liquid will do. For filtering, think about what you have. A fine-mesh sieve is great. Cheesecloth works, but you might need a few layers. Even a standard paper coffee filter can be used, though it’ll be slower.

Water quality and temperature

Tap water can sometimes mess with the taste. If yours is iffy, use filtered water. For cold coffee, you’re starting with cold or room temperature water. No need to heat anything up. That’s the beauty of it.

Grind size and coffee freshness

This is critical. You want a coarse grind, like breadcrumbs or coarse sea salt. Too fine, and you’ll get sludge and over-extraction. Too coarse, and you’ll get weak coffee. Freshly ground beans are always best. Grind right before you brew for maximum flavor.

For the best results, start with high-quality coarse grind coffee beans. This will significantly impact the flavor of your cold brew.

Coffee-to-water ratio

This is where you can really dial it in. A good starting point for cold brew concentrate is a 1:4 ratio of coffee to water. So, for every ounce of coffee grounds, use four ounces of water. You can adjust this later.

Cleanliness/descale status

Make sure your jars, pitchers, and any strainers are clean. Any old residue can impart funky flavors. It’s a simple step, but it makes a big difference.

Step-by-step (brew workflow)

1. Measure your coffee beans. Use a scale for accuracy, or a good scoop.

• Good looks like: Consistent amounts each time.
• Common mistake: Eyeballing it. This leads to wildly different results. Use a scale if you can.

To ensure consistent results every time, we recommend using a reliable coffee scale for precise measurements.

2. Grind your coffee beans. Aim for a coarse grind.

• Good looks like: Uniform, coarse particles.
• Common mistake: Using a fine grind. This makes your coffee bitter and hard to filter.

3. Combine coffee and water. Put the grounds in your container (jar, pitcher). Add cold or room temp water.

• Good looks like: All grounds are saturated.
• Common mistake: Not stirring enough. Some grounds might stay dry, leading to uneven extraction.

A durable glass pitcher is perfect for combining your coffee and water, allowing for easy steeping and storage.

4. Stir gently. Make sure all the coffee grounds are wet.

• Good looks like: A consistent slurry.
• Common mistake: Over-stirring. You don’t want to agitate it too much.

5. Cover and steep. Put a lid on your container. Let it sit at room temperature or in the fridge.

• Good looks like: It’s sealed and undisturbed.
• Common mistake: Leaving it uncovered. This can lead to weird smells or flavors from your fridge.

6. Steep for 12-18 hours. This is the magic window. Longer can get bitter.

• Good looks like: Patiently waiting.
• Common mistake: Rushing it. Under-steeped coffee tastes weak and sour.

7. Prepare your filter. Set up your sieve, cheesecloth, or coffee filter over another container.

• Good looks like: A secure setup that won’t spill.
• Common mistake: Not having enough layers of cheesecloth. You’ll end up with sediment.

8. Strain the coffee. Slowly pour the steeped coffee through your filter. Let gravity do the work.

• Good looks like: Clear, dark liquid dripping into the second container.
• Common mistake: Pouring too fast. This can overwhelm your filter and lead to a messy pour-through.

9. Filter again if needed. If there’s still sediment, run it through a clean filter.

• Good looks like: Clean, smooth cold brew.
• Common mistake: Settling for gritty coffee. A second strain takes seconds and improves the texture.

10. Dilute to taste. Your result is a concentrate. Mix it with water or milk.

• Good looks like: A balanced drink you enjoy.
• Common mistake: Drinking the concentrate straight. It’s super strong and probably not what you want.

11. Chill and serve. Add ice. Enjoy your homemade cold coffee.

• Good looks like: A refreshing beverage.
• Common mistake: Not adding enough ice. It’ll melt too fast and water down your drink.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Using a fine coffee grind	Bitter, muddy coffee; hard to filter	Use a coarse grind (like sea salt).
Under-steeping the coffee	Weak, sour, underdeveloped flavor	Steep for at least 12 hours.
Over-steeping the coffee	Bitter, astringent, overly strong flavor	Steep for no more than 18-24 hours.
Not saturating all coffee grounds	Uneven extraction, weak spots, sour notes	Stir gently after adding water to ensure all grounds are wet.
Using stale or pre-ground coffee	Flat, dull, lacking coffee aroma and flavor	Use freshly roasted beans and grind them just before brewing.
Not filtering thoroughly	Gritty texture, sediment in the bottom of your cup	Use a fine-mesh sieve, cheesecloth, or coffee filter. Strain twice if needed.
Drinking the concentrate straight	Overpowering bitterness and caffeine shock	Dilute with water or milk to your preferred strength.
Using poor quality water	Off-flavors that mask the coffee’s natural taste	Use filtered water if your tap water has a noticeable taste.
Not cleaning your brewing vessel	Lingering old coffee flavors	Wash your container thoroughly after each use.
Incorrect coffee-to-water ratio	Too strong or too weak for your liking	Start with 1:4 (coffee:water) for concentrate and adjust.

Decision rules (simple if/then)

• If your coffee tastes weak, then increase the coffee-to-water ratio for your next batch because you need more grounds for the same amount of water.
• If your coffee tastes too bitter, then shorten the steep time or use a coarser grind because over-extraction is the culprit.
• If you have sediment in your final drink, then use a finer filter or strain twice because your current filtration isn’t catching all the fine particles.
• If your coffee tastes sour, then steep it for longer or ensure your grind isn’t too coarse because under-extraction leads to sourness.
• If you want a smoother, less acidic coffee, then make cold brew concentrate because the cold water extraction process naturally reduces acidity.
• If you’re in a hurry, then make a larger batch of concentrate and store it in the fridge because it’s ready to go whenever you need a cup.
• If your water tastes off, then use filtered water because water quality significantly impacts coffee flavor.
• If you notice a lack of aroma, then grind your beans just before brewing because pre-ground coffee loses its volatile aromatics quickly.
• If your cold brew tastes “off” or stale, then check the cleanliness of your brewing vessel and filters because old residue can impart bad flavors.
• If you prefer a stronger coffee flavor without more caffeine, then use less water for dilution because you’re concentrating the coffee flavor.
• If you want to experiment with flavor, then add a pinch of salt to the grounds before steeping because salt can enhance sweetness and reduce perceived bitterness.

FAQ

How long can I store cold brew concentrate?

You can store it in an airtight container in the fridge for up to two weeks. It’s best consumed within the first week for optimal flavor.

Can I use any kind of coffee beans?

Yes, you can use any beans. However, medium to dark roasts often yield a richer, bolder flavor profile for cold brew. Lighter roasts can work but might be more delicate.

What’s the difference between cold brew and iced coffee?

Iced coffee is typically hot-brewed coffee that’s cooled down and served over ice. Cold brew is brewed with cold water over a long period, resulting in a smoother, less acidic concentrate.

Why is my cold brew cloudy?

This usually means your grind was too fine, or your filter wasn’t fine enough. A coarser grind and a second straining pass can help clear it up.

Can I make hot coffee using the cold brew method?

No, the cold brew method specifically relies on cold water extraction over time. Hot water is used for a different brewing process, like drip or pour-over.

How much caffeine is in cold brew?

Cold brew concentrate typically has more caffeine per ounce than regular drip coffee because of the higher coffee-to-water ratio used in brewing. However, dilution affects the final caffeine content of your drink.

What if I don’t have a lot of time to steep?

While true cold brew takes time, you can speed up the process slightly by using slightly warmer (not hot) water and steeping for a shorter period, maybe 6-8 hours. It won’t be the same as traditional cold brew, but it’s a quicker alternative.
